Have you not received updates to your Xiaomi Redmi 9 Pro for a long time, although new versions of MIUI have already come out for other devices? Or the phone has stopped checking for updates at all, giving out an error? This problem is familiar to many owners of budget Xiaomi smartphones, especially after 2-3 years of operation. In this article, we will analyze all possible reasons why your Redmi 9 Pro does not update, from banal connection errors to hidden manufacturer restrictions.
Now, the Redmi 9 Pro (codenamed joyeuse) came out in 2020, and its support officially ended in 2023, which means that global MIUI updates for this model are no longer coming out, but even then there are ways to get the latest security patches or upgrade to custom firmware, and we'll show you how to get around the restrictions if your phone is still capable of running new versions of the software.
It's important to understand that the update problem can be software (settings, server errors) or hardware (damaged memory, faulty Wi-Fi module), and we structured the material so that you can quickly diagnose the cause and choose the optimal solution, from simple actions to radical measures like unlocking the bootloader.
1.Official support complete: What it means for the Redmi 9 Pro
Xiaomi Redmi 9 Pro is a low-end product and its life cycle was initially limited, according to the company's policy, the Redmi 9 series received:
- 📅 2 years of major updates MIUI (before version 12.5)
- 🛡️ 3 years of security fixes (last in early 2023)
This means that from April 2023, the Redmi 9 Pro will no longer receive official updates via Settings → About Phone → System Update.
What if support is over, but you still need updates?
How to check if support for your model has ended? Go to Settings → About → MIUI version. If the last update is from the first quarter of 2023 or earlier, then the official updates for your region have stopped.
⚠️ Note: Installing unofficial firmware will void the warranty (if it is still valid) and may result in the device being blocked if there are firmware errors!
2. Internet connection issues: why the phone doesn't see the update
A common reason for the lack of updates is an unstable internet connection.Redmi 9 Pro checks for updates through Xiaomi servers, and if communication is interrupted or blocked, the system can show a message "No updates" even when there are.
Check the following points:
- 🌐 Wi-Fi connection: Mobile Internet updates are often blocked by the operator or phone settings. → SIM-maps and mobile networks → Data transfer and disable background restriction.
- 🔒 firewall VPN: Some applications (such as AdGuard or 1.1.1.1) block access to Xiaomi servers.
- 📡 DNS-servers: if you use custom DNS (For example, Google or Cloudflare, return the standard settings or try changing them to 8.8.8.8 and 8.8.4.4.
How do you force software updates when the Internet is working? Sometimes resetting the network helps:
- Go to Settings → Connections and Sharing → Reset network settings.
- Confirm the reset and restart the phone.
- After the reboot, check again for updates in Settings → About Phone → System Update.
💡
If the update is downloaded but not installed, try connecting to another Wi-Fi network (such as a hotspot from a friend's phone), sometimes the problem lies in the ISP blocking traffic.
Xiaomi server errors: When the problem is not on your side
Xiaomi is spreading updates across waves, meaning that even if the update is already out, your phone may receive it later, and the company’s servers are sometimes overloaded or temporarily unavailable in certain regions.
How do you know if Xiaomi is the problem? Compare your situation to these signs:
| Symptoms. | Probable cause | Decision |
|---|---|---|
| Phone shows “No updates”, but the forums write about the release of the new version | Delayed wave distribution | Wait 1-2 weeks or change the firmware region |
| Error “Cannot download service pack” (code 404 or 500) | Xiaomi server is not available | Try it later or use a VPN to change your region |
| Update is downloaded but not installed (the “packet damaged” error) | Incomplete load due to communication breakdown | Delete the downloaded file and try again |
If you suspect a server failure, check their status on independent resources, for example:
- 🔗 Downdetector (monitoring Xiaomi falls)
- 🔗 Forum MIUI SU (section “Updates»)
💡
If the update is critical (e.g., fixes a vulnerability) and Xiaomi servers have been down for days, consider manually installing via Recovery or Fastboot.
4.Insufficient Memory: The Hidden Cause of Update Failures
The Redmi 9 Pro comes with 64 or 128GB of storage, but even that may not be enough to install the update.The system requires a minimum of 2-3GB of free space in the /data partition, otherwise the process will be interrupted with the “Not enough memory” error.
How do you make room right? It's not enough to just delete the photos, you have to clean them up.
- 🗑️ App cache: Settings → Annexes → Application management → Clear the cache (select the most “heavy” apps).
- 📂 Downloads: The Download folder often contains unnecessary files (especially the ones you need to download) APK media).
- 🔄 Duplicate files: Use apps like Files by Google to find repetitive photos or documents.
- 🎮 Game data: games of the type PUBG Mobile or Genshin Impact can weigh a few gigabytes. remove unnecessary or transfer to SD-map.
Free ≥3GB of memory | Disable VPN and firewall | Connect to stable Wi-Fi | Charge battery ≥50% | Delete old update files from Download-->
If there is not enough space after cleaning, try:
- Transfer applications to SD-card (if supported).
- Remove unused system applications through Settings → Apps → Show everything (carefully – do not delete service ones!).
- Reset your phone to factory settings (pre-do backup!).
⚠️ Warning: If the update is not installed after cleaning the memory, check the internal drive status. Damaged sectors may block the recording of new files. AIDA64 (section»).
5.Blocking updates due to system modifications
If you ever:
- 🔓 Unlocked bootloader (bootloader),
- 🛠️ Install Magisk or other modules for root rights,
- 📦 Changed system files (such as fonts or animations),
Your Redmi 9 Pro may be blocked from receiving the OTA-Xiaomi checks the integrity of the system partition before installing updates, and any changes result in the error "Device modified. Update impossible».
How do you get around the lock? There are two ways:
- Restore your firmware: Download the official ROM for your model from en.miui.com, run it through Fastboot using the Mi Flash Tool, which will delete all data and return the phone to the factory state.
Install the update manually through Recovery
1. Download the full service pack (not incremental!) from the Xiaomi.eu or 4PDA forum.
2. Rename the file to update.zip and place it in the root of the phone's memory.
3. Enter Recovery (turn off the phone, then press Power + Volume up).
4. Select Install update.zip and confirm installation.If you use custom software (such as Xiaomi.eu or LineageOS), OTA updates may not work because of:
- 🔧 Version inconsistencies MIUI (For example, trying to install a global update on Chinese firmware).
- 🔒 Xiaomi’s lack of signature (castomy builds often fail integrity checks).
6. Hardware malfunctions: when the "iron" is to blame
If all software methods have been tried, but the Redmi 9 Pro is still not updated, the problem may lie in the hardware.
1. Damaged Memory (eMMC)
Symptoms:
- 🐢 The phone slows down when writing / reading files.
- 🔄 Applications are closed spontaneously.
- ❌ Updates are broken at the unpacking stage (error "Can not mount the section»).
Diagnosis:
- Run the memory test through AIDA64 (Section "Storage → Read/Write Test").
- If the speed is below 50 MB/s, the drive is worn out.
2. Faulty Wi-Fi/Bluetooth module
If the phone cannot connect to the network to download the update, check:
- 📶 Does Wi-Fi work in other applications (e.g. YouTube or Speedtest).
- 🔌 Does the phone connect to other networks (e.g., a mobile access point).
3. Battery discharged or bloated
Upgrade requires a minimum of 50% charge. If the battery is worn out (capacity below 70%), the phone may interrupt the process due to a sudden shutdown. Check the battery status in AIDA64 (Battery section) or through code ##4636## (Battery Information menu).
⚠️ Warning: If the phone shuts down when charged above 30% or the battery is swollen (see above the raised screen), do not try to upgrade - this can cause the device to fail completely.
7.Regional restrictions: why your country doesn't have updates
Xiaomi distributes updates by region, and sometimes updates for one country are released later (or not at all).For example, Redmi 9 Pro for India (IN code) could receive updates longer than the global version (Global).
How do you check your area?
- Go to Settings → About Phone → MIUI version.
- Look at the postfix in the build number (e.g. V12.5.3.0.RJZMIXM): RU – Russia, IN – India, EU – Europe, CN – China.
If your region is “lagging behind”, you can change the firmware to a more relevant one:
- Download ROM for another region from the official website.
- Sweep it through Fastboot (instructions are available on 4PDA).
- ⚠️ Important: After the change of the region, you can stop working: 📡 LTE-ranges (if the firmware does not support your frequencies), 💳 Google Services (in Chinese version) MIUI), 🗣️ Voice assistants (for example, Alice from Yandex).
💡
Changing the firmware region may solve the update problem, but it can lead to loss of functionality. Always check the compatibility of the model (joyeuse for Redmi 9 Pro) with the selected version of MIUI.
